Our invention relates to improvements in pressure regulators for filling mechanisms,

and it consists inthe combinations,

described and An object of our invention is toprovide a'filling mechanism in which a novel means is employed for maintaining a predetermined the pressure in the liquidtank and the pressure in the high-pressure chamber, irrespective of the pressurel in the latten I f A further object or our invention is to propermit a predetermined amount of li uidtm pass to the bottles.- I 3 a A further object of our inventionis to pro vide a device of the type described which will fill all the bottles atan even height. 7

A further object of ourinvention is to pro vide a device of thetype descibed which obviates the need of valves, (pressure'reducers,

and other devices dispose between the carbonator and the filling machine which inter-- fere with the general travel ofthe carbonated water. \Nhen the travel of the carbonated water is interfered with, as when drawing the Water through a wire mesh, the velocity of the water is increased and the water is substantially broken up, thus causing a portionof the gas to escape therefrom. 1 A further object of our inventlonis to provide a device of the type described which has adjustable means for varying the amount of liquid entering each of the bottles.

Other objects and advantageswill appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims. 1 I Our invention isillustrated in the accompanying drawings, forming part of this ap-' plication, in which Figure 1isa side elevation of the device, portions thereof being shown -in section, and Figure 2 is an enlarged sectional view of aportion'of the device. v I

- In carryingout our invention, we provide a carbonator 1 indirect connection with"a filler tank 2 byxmeansof a pipe 3." Fill-j ing valves 4 are carried by the filler tank 2 construce with air under pressure;

and are adapted to permit a liquid 5 which is in the filler tank to pass therethrough. Bottles 6 are-disposed in communication with the valves i and adapted to receive the liquid 5as it passes throughthe valves.

A water check tank 7 having a liquid 8 therein is provided with a high pressure chamber '9. Pipe lines 9a provide commu-,

nication between the pressure chamber 9 and the filling for supplying the high pressure chamber 9 the chamber 9, the high. pressure chamber 9 is forced downwardly, causing the liquid to rise in the water check tank?- to a point indicated at 11. Open- 'ings' 12 are disposed in the high *pressure chamber adjacent the lower edge thereof forpermitting the liquid and the air to pass theret-hrough. It is obvious that the pres sure'in the high pressure chamber 9 is greater than thepressure above the liquid in the water check tank 7, the differencebeingjthe weight of the liquid from the point indicated at 11 to a point inalignment with the openings l2. A pipe 13 permits communication between the water check tank 7 is equal to the air pressure in the water check tank.

A pressure release valve A consists of a body portion 1.4- The body portion 14 is provided with an arcuate-shaped compartment 15 which has an inlet opening 16 and an'outlet opening17; atone end to the inlet opening 16 and at the other end to the filler tank 2. The pipe 18 permits the air'withinthe fillertank-2 to pass therethrough and into the compartment 15. An adjustable set screw 19 is movably disposed in the body portion 14 and adapted to limit the amount of air passing through the outlet opening from the compartment 15.

Abottom plate 20 and a diaphragm 21 are removably secured tothe body portion 14 by means ofscrews 22. Diaphragm discs 23 and 24 are secured to the diaphragm 21 and'to each other. The discs 23 and '24 are lockedtogether by a posed upon a threaded 'extention 26 of the valves 4. An inlet 10 is provided and the filler tank 2, and the air pressure in the filler tank A pipe 18 is secured lock nut 25 which is dis As the air entersi liquid 8' which is in the datat3 T e whi h the disc 23. The extension 26 is provided with an opening 27 for receiving a guide 28 which is rigidly secured to the bottom plate 20.

The disc 23 is provided with a valve 29 which is adapted to engage with a valve seat 30. The valve seat 30tis provided with an opening 31 for permitting air to pass therethrough when the valve has been moved away therefrom. V V I -'.'Aic'up-shapedcover 32"is secured t'o the body portion l4by screws 33. The cover 32 is provided with an annular flange 34 which is spaced away from body portion 14 so as tov provide a passageway 35. An out-let passageway 36 provi es a communication between the passageway and the outlet opening 17. Openings 37 are provided in the cover-32 for permitting air.

to pass outwardly therethrough. 3

A valve adjusting screw 38 is disposed in the center of the cover 32 and provided with an opening theret-hrough. justed tacts with Y lie valve rod 42 extends through a Wi e B 46, and into the opening the adjustable .valve' screw .38.."

pression spring 48 is disposed concentric with the lv 20, andthe other end disposed in communication with the high pressure chamber 9.

From the foregoing description of "the various parts of the device, the operation.

thereof may be readily understood.v It: will be observed that the air pressure in the filler".

to the air pressure in the liquid check tank, and that the pressure in the bottle tank is equal 6 is equal to the pressurein the high pressure chamber 9.-

The main purpose of the invention is to provide means for maintaining a difference of approximately five pounds of pressure between the air 7 the. air pressure in the highpressure chamber. The means for doing this is the valve A. It is air pressure in the is indicated generally at X. The air pressure in the compartment 15 is equivalent to" the air pressure in the filler tank 2. a When there are at least five pounds more'pressurein the'c'h'amber X than in the compartment15, the valve 29 is held against the valveseat 3Q preventingthe air from escaping through theopening 3 1.

for instance, if there are thirty pounds of air; pressure in the high pressure chamber, thereshould only be twentyfive pounds of air pressure in the filler tank, and the valve A could headjusted so that if the pressure in the filler tank; should rise to twenty-five and onehalf pounds, as to permit the-additional-air pressure toescape through the. openings. 31 and 37. This means-includes'the adjustable valve screw 38 which may be; moved inwardly, to increase the tension of the spring .48 so that it, will take less air pressure to movethe diaphragm, 21, so that the valve 29will be: spaced away from the valve seat 30 and permitsair'toescape there:- the. pressure uponithe diaphragm 2l', by 'means of, the springf48, may: be, varied. so that. the diaphragm 21 may be the valve would be actuated so moved by the-air pressure 7 in-the filler tank hy'aniincrease of anywhere T 1} fmctionof one pound to five pounds of air pressllre; a A If the difference of five Zpounds. pressurebetween-the'filler'tankiand the high pressure chainh fill the bottles uniformly owing to the air-under fpressure in-the bottles.
